Using these Sferra Catena Boudoir Shams is as simple as placing them on your bed. They'll instantly add a touch of style. When it's time to clean them, use a gentle cycle in warm water in your washing machine. Avoid using bleach as it can weaken the fabric and cause yellowing. Also, don't use fabric softener. Wash dark - colored shams separately. Tumble dry on low heat and take them out while they're still a bit damp. You can steam iron them on the 'cotton' setting, but do it on the reverse side of the fabric.
